Abstract

A novel and efficient method for selective Michael addition of 2-pyridones to ethenesulfonyl fluoride (ESF) and 1-bromoethene-1-sulfonyl fluoride (BESF) has been developed for constructing a class of pyridonyl aliphatic sulfonyl fluorides and pyridonyl vinyl sulfonyl fluorides in good to excellent yields. This practical method features easy operation, wide substrate scope, and mild reaction conditions.
